STOVE.

Application filed November 23, '1925. Serial No. 70,940.

, This invention relates to improvements in heating apparatus and has particular reference to an improved stove or furnace. y n

An important object of the invention 1s the provision of a stove designed so as to obtain the utmost heating efficiency forheating the interior of dwellings and the like.

"A further object of the invention is to provide a stove arranged so as to produce the maximum circulation and radiation etliciency.

Another object of the invention is the provision of a stove designed so as to obtain the utmost heating efficiency from the fuel.

A still further object of the invention is the provision of a stove of comparatively simple yet durable construction designed so as to be placed upon the market at'a reasonable cost.

Other objects and Vadvantages of this invention will become apparent as the description progresses. In the accompanying drawings forming a part of this application and in which like numerals are employed to designate corresponding parts throughout the same:

Figure 1 is a longitudinal sectional view through a stove constructed in accordance with my invention,

Figure 2 is a top plan view of the same,

Figure 3 is a transverse sectionalview taken on the line 3-3 of Figure 1,andY

Figure 4 isa bottom plan view taken on the line 4:-4 of Figure 1.'- In the drawings, wherein for the purpose of illustration is shown the *preferredV emlbodiment of myy invention, the numeral 10 generally indicates the outer casing of my improved stove preferably of longitudinal 4o Vcylindrical formation constructed of durable metal. AThe lower extremityof the casing or 'shell- 1() is enclosed by a circular bottom plate 11 while the upper end is open.

Arranged in the upper central portion of the casing 10 concentric with the outer casing is an inner cylindrical casing 12 perforated adjacent its upper end. This member is disposed in spaced relation above a cylindrical structure 13 forming the fire pot, the lower end of therire pot-13 resting upon 'the bottom of the outer casing 12 while the upper extremity flares outwardly and contacts with the side walls of theouter shell. This fire pot is of decreased diameter and arranged concentricallywith the outer casing and is preferably constructed of fire clay ol.

suitable material. `The interior of the fire pot 13is provided with a plurality of circularly 'arranged lugs ltupon which al com.- mony form of grate 15 is mounted.

y With particular reference to YFigures 1 and t, it will be seen ythat the outer casing carries a fuel door 16 which is in transverse alignment with an opening formed in the fire pot. A feed chute extends between the door 16 and the opening formed in the lire pot. As is customary, an ash door 17 is also provided, the structure in this instance being similar to the formation of the fuel door structure.V Mounted in the annular chamber formed between the inner and outer casings are a plurality of vertical air conducting pipes 18 arranged in spaced relation in the annular chamber.` These pipes extend from the lower closed end ofthe vouter casing to Va vposition projecting above the upper' end.

Arranged in alternate relation with the pipes 18 are a plurality of comparatively short pipes 19-preferably of'rsmaller diameter extending from the lower closed end of the casing and bent in an arc at the'upperextremity so as toA communicate with the inner cas- Ying 12. The pipes 19 connect with the lower extremity of the inner casing and communicate with the interior thereof so as to permit free circulation of air therethrough.

y The entire structure is supported by aY plurality' of feet 20,*in the presentinstance four, arranged in spaced vrelation and `detachably secured to the bottom plate 11.

Y As will be readily noted with reference to Figures 1 and 3, a plurality of vertical partitions 21 are secured between the inner and outer oasings, these-partitions being disposed between the circulating pipes 18 and 19. The partitions 21 terminateat a spaced distance 'from the topi` and'bottom of the heater'to conduct the heatedv air vertically upward in the intermediate portions of the stove vadjacent the conducting pipe 18 and 19, and permit distribution of the air at the upper. and lower ends to maintain a constant pressure and temperature.

Mounted 4on the upper end ofthe stove is a hollow cover 21 composed of a pair of metallic plates of circular formation arranged in spaced relation and connected by an annular ring 22. This ring is perforated to permit convenient circulation of the air. Formed on the outer periphery of the hollow cover is an arcuate downwardly extending flange 23, the structure being so arranged as iin' `between the inner and ontericasings. This smoke is conductedthrough a smoke pipe 24 communicating with the outer casing adjacentftlie upper end. It is obvious, from the construction shown and described, that the air entering the conducting :pipes is heated `and elevated and distributed through `the hollow cover 21. It is contended that the particular construction embodied in applicants stove obtains the greatest heating sur- `face )ossible and thus a maximum ofheatingle 'ciency isobtained `from the fuel.

Itis to be understood that the forni of my invention herewith shown and described is ,susceptible otniodiiication and that various changes as to the shape,.size and arrangelment of parts may be resorted to without departingfrom the spirit of the invention or `the scope of the subjoined claims.

`IJIaving thus described iny invention, I claim:

41. A stove comprising, in combination, an outer cylindrical casing, a bottom plate eiiclosing the lower end of the said casing, a .lire box positioned in the centrallower portionof the casing `flaring outwardly atits upper extremity, aninterior cylindrical casing ymounted inthe upper central portion, a-

plurality of airconducting pipes extending verticallythrough the chamber formed be- `tweenthe said inner and outer casings, aphii-ality ot'` shorter conducting pipes extending from the bottom plate and communicating with the lower `portion of the inner casing, .means `for supporting `the structure, and a hollow cover embodying a pair of spaced plates connected by a perforated ring, Ithe said hollow cover being detachably mounted `on the upper end of the said oasings.

2. A stove comprising an outer cylindricalcasing, a circular bottom plate enclosing and a hollow cover eiijibodying a pair of spaced plates connected by a perforated an- `nular ring, the said hollow coverbeing inovably mounted on the upperend of the casings.

A stove comprising an outer cylindrical casing enclosed atlthe lower" endby a circular bottom plateVsuppOltllg `feet secured to the lower surface ot' the bottom plateand adapted `to support the easing ;in an elevated position, a tire box mounted centrally in the lower portion of the said outer casing, a grate `supported in the lire box, an inner casing arranged concentrically within the `outer casing and in spaced relation there- `trom, the lowerend of the inner casing being enclosed by a bottom plate and having aperltnreslormedadjacent,the lower end, a pluiality of longitudinalairconducting pipes extending within the outer casing in vertical arrangement spaced from the inner casing i and connecting withl openings formed in the bottoinplate ofthe outerlcasing, a plurality of comparatively short air conducting pipes extending from the lower portion of the outer casing and having their upper ends connected withfthe apertures in the lower `endof the inner easing and their lower ends connected with apertures in the bottom plate of, the outer casing, and a hollow cover composed of` a pair `otrhorizontal spaced plates having alined openings through which the longitudinal air connecting pipes project and an annular ring connecting the plate apertured to permit the escape of hot air from the interiorcasiiig. l
